The creation of extremely strong, flexible, high resolution displays has been made possible with the development of “nano-pixels”, pixels that are just a few hundred nanometres across.

The researchers from Oxford University used phase change materials (materials that can change from an amorphous to a crystalline state), and sandwiched them between transparent electrodes to create a surface that functions like a pixel.

While still very much in the early stages of development, the research could be used in multiple technological applications, including creating extremely strong, flexible displays and surfaces.
